reading comments so far.. seems from people who have not tried how the current situation is. Yes most of these "cant say" worked 3+ years go. But it is harsh employer-driven market now. 100 candidates for 1 position.

The question is baked and mandatory in most forms, and there's no "cant say" - only about 20% do not ask it, all else.. have it. And it is the easiest filter for the above 100 candidates, so.

Negotiation phase? hah. You are lucky if you get a rejection e-mail. Most don't bother with even that, regardless the importance of the role. And you never know if the number was too high, or completely irrelevant.
